With consent of the governed: SEC's formative years

The Securities and Exchange Commission, established in 1934, has achieved a uniquely high reputation for effective regulation. The SEC succeeded in large measure because of the initial strategy developed by its founders. Led by Joseph P. Kennedy, James M. Landis, and William O. Douglas, the SEC sought to restore public confidence in the capital markets and induce regulated interests to help enforce public policy. These interests included the accounting profession, the organized securities exchanges, and the brokers and dealers operating in the over-the-counter market. In each case, the SEC encouraged the strengthening of regulatory structures within the private sector, using its power and influence to promote what later came to be called the “public use of private interest”.     

A comparison of different delinquency measures derived from self-report data

The purpose of this research was to explore different ways of using self-report data to derive measures of juvenile delinquent behavior. The subjects were 161 public school children in the Omaha area, and 1,030 public school children and 665 adjudicated delinquents in the metropolitan areas of Baltimore, Indianapolis, and Phoenix. The Omaha youths responded to twenty-eight self-report items two times with an intervening period of three weeks and then rated the items for seriousness. Four measures of delinquency were derived from the data: frequency of activity, diversity of activity, seriousness of activity, and progression into delinquent behavior. The four measures were shown to be highly reliable and strongly intercorrelated; none was shown to be consistently better than the other three. Rated seriousness and reported frequency of behavior were highly negatively correlated, giving support to the use of frequency measures in building delinquency scales. All four scales showed differences within the Omaha sample as a function of sex, age, and birth order; but the differences were not always in the same directions when the four measures were used.     

The autodegradation of deoxyribonucleic acid (DNA) in human rib bone and its relationship to the time interval since death

This research explored the feasibility of using the degradation rate of deoxyribonucleic acid (DNA) in human rib bone to determine the time interval since death. Postmortem human rib samples were surface sterilized and incubated under sterile conditions in either high or low humidity conditions at room temperature for a period of weeks. At selected times, portions of the bone were cut away, and the DNA from these samples was extracted and subjected to strand separating gel electrophoresis. The DNAs in the gels were transferred to a nylon membrane, preserving their relative positions as in the gel, and probed with radioactive total genomic human DNA. Autoradiograms produced were scanned and digitized. When the samples were incubated under identical conditions, the degradation rate of DNA in samples from different individuals appeared very similar. The DNA degradation rate may vary with temperature and humidity more than it varies between individuals.     

Production efficiency versus bureaucratic self-interest: Two innovative processes?

This article reports on a study of technological innovations in state and local government agencies. The study was based on an aggregate analysis of 140 previously published and unpublished case studies, in which a closed-ended questionnaire was used to extract information from the case studies. The main hypotheses and findings of the study concern the possible existence of two innovative processes, one that emphasizes service improvements but that does not necessarily lead to enduring incorporation of the innovation (production efficiency), and the other that emphasizes incorporation even where the innovation may not have produced a demonstrable service improvement (bureaucratic self-interest).This study was supported in part by a grant from the Office of R&D Assessment, National Science Foundation, though the author alone is responsible for the views expressed here.
